(I'm jumping into the middle of the thread...)

Sorry, but John's the "most correct" on this one, although I see
Greg's side: some applications won't have a compatibility problem from,
say, 10.x to 11.x ... but many do.

Even *HP* internal people have run into this problem.  My wife's group
in Cupertino hit it from 10.x to 11.x, for example.

Even *HP* admits the problem: they offer migration consulting to migrate from
10.x to 11i.  (They might call it "upgrade consulting" or something)
...I got an offer from them yesterday about the service!

HP hasn't had to offer that for any MPE XL or MPE/iX version changes :)
